'''''Poa triodioides''''', synonyms including '''''Austrofestuca littoralis''''', is a species of flowering plant in the grass family Poaceae, native to southwestern and southeastern Australia and to New Zealand.<ref name=POWO_418259-1/>

==Taxonomy== The species was first described by Jacques Labillardière in 1805 as ''Festuca littoralis''. It was subsequently placed in several other genera. It was first transferred to ''Poa'' in 1864 by Joseph Dalton Hooker, but under the illegitimate name ''Poa littoralis'',<ref name=POWO_418259-1/> which had already been used for a different species.<ref name=IPNI_325394-2/> It was transferred to ''Arundo'' in 1836 by Carl Bernhard von Trinius as ''Arundo triodioides''.<ref name=POWO_418259-1/><ref name=Trin36/> (''Arundo littoralis'' had already been used.<ref name=POWO_390891-1>{{Cite POWO|title=''Arundo littoralis'' P.Beauv..|id=390891-1|access-date=2024-11-27|mode=cs1}}</ref>) ''A.&nbsp;triodioides'' was then the basis for the legitimate name in ''Poa'', ''Poa triodioides'', published by Zotov in 1943.<ref name=IPNI_418259-1/><ref name=POWO_418259-1/> In 1976, Evgenii Alexeev placed it in his new genus ''Austrofestuca'', which he had elevated from a section of ''Festuca'', as ''Austrofestuca littoralis''.<ref name=IPNI_17558-1/><ref name=IPNI_391266-1/> ''A.&nbsp;littoralis'' was at one time the only species in the genus. ''Austrofestuca'' has since been treated as a synonym of ''Poa''.<ref name=POWO_17558-1/>
